Multi-Shot Video Editing Using a Common Embedding Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in video editing is ensuring spatio-temporal consistency of edits across multiple shots, particularly in post-production, where artists spend significant time to maintain uniformity in digital makeup, which is tedious and time-consuming, especially for non-professional users.
Innovation Solution
A method and apparatus for editing multiple video shots using a common embedding space to propagate edits across sequences, utilizing a universal mosaic and visibility maps to ensure consistent edits, incorporating 3D face models for tracking and color correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual editing of each shot is performed to ensure spatio-temporal consistency, then editing quality is improved, but editing time and artist workload increase significantly
Solution Approach 1:
The patent creates a universal mosaic that serves as a master template containing the edited object. This universal mosaic is then copied and applied to multiple shots simultaneously, ensuring consistent edits across all sequences without manually editing each shot individually. The embedding space representation enables this copying mechanism to maintain spatio-temporal consistency while dramatically reducing editing time.
Solution Approach 2:
The universal mosaic acts as a multi-functional element that can be applied across different shots and sequences. By creating a single edited representation in the universal embedding space, the system achieves universal applicability across multiple video sequences, eliminating the need for repetitive manual editing while maintaining consistency.
2Manufacturing precision
If professional artists manually edit each shot for digital makeup consistency, then editing quality is improved, but productivity decreases due to tedious repetitive work
Solution Approach 1:
The system enables self-service editing by automatically propagating edits across multiple shots using the universal mosaic and embedding space technology. The editing process becomes self-propagating, where a single edit automatically applies to all relevant sequences without requiring continuous artist intervention, thereby maintaining high consistency while dramatically improving productivity.
Solution Approach 2:
The edited object in the universal mosaic is copied across all shots that contain the target object. This automated copying mechanism ensures that digital makeup edits remain consistent across all sequences while eliminating the tedious repetitive manual work, thus improving artist productivity without sacrificing quality.
3Ease of operation
If traditional editing methods are used for non-professional users, then ease of operation is maintained, but the ability to achieve consistent edits across multiple shots becomes impossible
Solution Approach 1:
The universal mosaic and embedding space act as intermediaries that bridge the gap between simple user operations and complex editing requirements. Non-professional users can perform simple edits on the universal mosaic, and the system automatically handles the complex propagation and consistency maintenance across multiple shots, making advanced editing accessible to casual users.
Solution Approach 2:
The system enables non-professional users to achieve consistent edits by allowing them to make a single edit on the universal mosaic, which is then automatically copied to all relevant shots. This copying mechanism eliminates the need for users to manually edit each shot while ensuring professional-level consistency, thereby maintaining ease of operation.
